Hormonal Regulation of Hormone Release. Hormonal regulation of hormone release involves a hormone binding to its receptor on an endocrine cell to regulate hormonal secretion.

Tropic hormones may also stimulate proliferation of endocrine cells.or polar hormones, tropic hormones stimulate endocrine secretion by stimulating cell secretion; that is, exocytosis.
